I'm a diehard kayaker, and had the Sea Eagle Fast Trak for a few years - it's a great boat!  I had the #385 - it could be paddled solo or tandem.  Had a good skeg, so tracked like a hardside, was super-stable; and the sides were low for easy paddling and re-entry if you're swimming/diving.  The skeg was removable, for whitewater - it was rated to Class III (so you know it was durable!!)  When packed away, it was about the size of a large duffel, in our case, it stored nicely in the dinette of our 5er.  And re the OP's question: the floor was removable, so it was easy to towel-dry the boat completely before I rolled it up.  The only reason I sold it (to a fellow RVer) is that we're now snowbirds with a condo/garage, where I can store my hardsided boats
